怎样在logic的代码里面和流程的代码里面调用共用的方法？

狮子心

bex5v3.3
如图，在logic/code/dsrc  里面的Biz.java调用了其他的文件，然后我的流程事件里面的biz\process\case\dsrc 里的CaseProcess.java也要调用Biz.java同包下的文件。默认没包名，我怕影响功能没有改包名。直接拷贝了那几个文件过去。不过现在也报错


Native Library E:\myworkspace\wex5\BeX5_V3.3_pre\java\jre1.7\bin\jacob-1.18-x86.dll already loaded in another classloader

可以看得引用了dll，dll already loaded in another classloader报错。怎么解决？方法最好是像平常正常项目那样引用一份文件就好，维护方便。

如果是多个目录都要用同一个dll，可以把dll放到BusinessServer\WEB-INF\lib下或者创建一个公共的lib目录，需要的地方引用公共的lib目录
